PROCESS FOR USE IN THE FORMATION OF ATTACI-IING MEANS FOR BAIL-EARS.

Specification of Letters Patent.

Patented Aug. '7, 1917.

Application filed November 15, 1915. Serial No. 61,536.

To all whom it may concern:

Be it known that I, HENRY A. BEYER, residing at Corona, Long Island, inthe county of Queens and State of New York, have invented certain newand useful Im provements in Processes for Use in the For- 'mation ofAttaching Means for Bail-Ears and the like, of which the following is aspecification.

This invention relates to an improved process for use in the formationof attaching means for bail ears and the like.

A particular object of the invention is to provide a process by the useof which the bail ear is rendered stronger and of more uniform strengththan heretofore.

The more specific object is to provide a process for the formation ofthe attaching means for the bail ear whereby the particular portion ofthe material from which the attaching means is formed is drawn from theadjacent portion of the material to which the ear is to be attached insuch manner as not to be subjected to any such tensile or shearingstrains as would detrimentally affeet its strength.

Other objects and aims of the invention, more or less specific thanthose referred to above, will be in part obvious and in part pointed outin the course of the following description of the elements,combinations, arrangements of parts and applications of principles,constituting the invention; and the scope of protection contemplatedwill be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of thisspecification, and in which I have shown a merely preferred form ofembodiment of the invention:

Figure 1 is a side elevational view of a portion of a receptacle, havingan ear formed thereon constructed in accordance with the provisions ofthis invention.

Fig. 2 is a vertical sectional view taken substantially upon the planeof line II-II of Fig. 1.

Fig. 3 is a side elevational view of a portion of the receptacle showingthe same as it appears in accordance with the first step of thisprocess.

Fig. A is a vertical sectional view taken substantially upon the planeof line IVIV of Fig. 3.

Fig. 5 is a view similar to that shown in Fig. 3 but showing a furtherstep of the process.

Fig. 6 is a vertical sectional view taken substantially upon the planeof line VI-VI of Fig. 5.

Fig. 7 is a view similar to that shown in Fig. 3 but showing a stillfurther step in the process and:

Fig. 8 is a vertical sectional view taken substantially upon the planeof line VII- VII of Fig. 7.

Referring to the drawings for a description of the structure illustratedtherein, the reference character L indicates the wall of the pail, orother article upon which the ear is formed.

The reference character G indicates the button which is fixed to thewall L and which I constitutes the essential element of the ear. Thebottom wall of the button is apertured and flanged inwardly as at 2 forreceiving the bail H as is the usual practice.

The means by which the button G is fixed to the wall L consists of anannular rib 3 which is formed upon the wall and which provides a pocketupon the wall within which the outwardly flaring edge of the button isreceived.

The button is of such size as to fit snugly within this pocket, andafter the button has been placed therein the rib is bent over upon theflaring edge of the button, thereby locking the button rigidly in place.

In Figs. 3 to 8 the preferred process is illustrated by means of whichthe rib 3 is produced.

In accordance with this process the portion of the wall L, where it isdesired to form the ear, is first pressed outwardly by suitably formeddies to form a projection 4:, as seen in Figs. 8 and 4:. The projection4:, is preferably circular and is preferably of somewhat greaterdiameter than the diameter desired for the ribs.

This pressed or bulged out portion 4 has its outer portion orcircumference formed by curved portions of the material. This insuresthat the material utilized in forming the'bulged portion will not be cutor creased so as to weaken the same. Neither is the ma terial formingthe portion 4: made appreciably thinner as the dies are so formed andutilized as to draw or stretch somewhat the material surrounding thebulged portion.

As a second step, the annular marginal portion of the projection 41; ispressed back again by suitable dies into the plane of the remainder ofthe wall as seen in Figs. 5 and 6. This reduces the size of theprojection 4: and makes it of a diameter substantially that desired forthe diameter of the rib 3. The

sides .5 of the projection now are substantially at right angles to theplane of the wall, whereas at the end of the step shown in Figs. 3 and 4they were at an incline or curved,

ducing the right angular disposition of the sides 5 of the projectionavoids undue localization of stretch, such as might otherwise tend tofracture the material at some point. In bending the metal out in curvedcross section, as in Figs. 3 and 4:, very little localized stretch isfelt. The stretching is gradual and uniform over a relatively wideexpanse. The metal thus drawn is simply bent back again to form theright angularly disposed side walls practically without any stretchingwhatever.

As a third step in the process, the central portion of the projection41:, is pressed back again by suitable dies to the plane of the wall Las shown in Figs. 7 and 8. In this step a portion of the sides 5 isbent, or folded, inwardly, thereby reducing the .height of said sides,and forming rib 3.

The rib thus formed is integral throughout with the wall L. It is ofdouble thickness, and is, therefore, of great strength. There isabsolutely no danger of a leak as no opening of any kind has been formedthrough the wall. The inner surface of the receptacle is left smooth andeven.

After the rib is, formed, the button is, positioned and the ribispressed or bent over bysuitable dies, as above described with regardto Figs. 1 and 2. The operation of pressing over the rib causes theangles 7 and '8 to be-mashed down into quite sharp cornerswhich abuttogether and effectually close any space which may have previouslyexisted between them and at the'same time this operation renders thesurface practically unbroken.

It will be seen that, by means of my construction and my process forproviding the same, the ear is to all practical purposes an integralpart of the receptacle. The process is also carried out in such a way asnot to weaken the material or the receptacle or form any aperturetherein.

As many changes could be made in this construction without departingfrom the scope of the following claims, it is intended that all mattercontained in the above description, or shown in the accompanyingdrawings shall be interpreted as illustrative only and not in a limitingsense.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

ing an annular rib upon a member, which consists in first pressing out aportion of the member to form a projection thereon having an annularoutstanding wall portion, and then pressing inwardly a part of theoutstanding wall to form an annular wall portion substantially parallelto the remainder of said first mentioned annular wall portion. as seenat 6 in Fig. 4. This method of pro- 2. The herein described process offorming an annular rib upon a wall, which consists first in pressingoutwardly a portion of the wall to form a projection thereon of somewhatgreater diameter than the diam- 1. The herein described process off0rm-- eter desired for the annular rib, thenpressing inwardly anannular marginal portion of said pro ection suficient to reduce thediameter of the projectionto that desired for the rib, and thereafterpressing inwardly the central portion of the reduced projection, so asto leave outstanding only the .annular wall of the reduced projectionand an annular wall parallel therewith extending from the outer edgethereof inwardly to said central portion.

.3. The herein described process of forming a bailear which consists inpressing outwardly a portion of the member to form a projection thereonhaving an annular out-' standing wall portion, then pressing inwardly apart of the outstanding wall port1on to form an annular wall portionsubstantially parallel to the remainder of the' first mentioned annularwall portion, then positioning a bail-carrying button within the spacedefined by the annular wall portions, and finally bending inwardly saidannular portions into engagement with the bail-carrying button to lockthe bail-carrying buting the rib member about a portion of the V earmember.

5. The herein described process of forming an annular rib integrallyWith a piece of sheet metal, which consists in bending out in onedirection that portion of the metal from which the rib is to be formedand then bending back a portion only of said metal previously bent out.

6. The herein described process of forming a rib integral With a pieceof sheet metal Within the marginal confines of said piece of sheetmetal, Which consists in first stretching that portion of the metal fromWhich the rib is to be formed, bending the stretched part to form a Wallupstanding at approximately right angles to the surrounding unstretchedportion of the metal, and then bending back a portion only of said WallCopies of this patent may be obtained for five cents each, by addressingthe into substantial parallelism With the remaining upstanding portionof said Wall.

7. The herein described process of forming an annular rib integrallyWith a piece of sheet metal Within the marginal confines of said pieceof sheet metal, which consists in first stretching an annular portion ofsaid piece of sheet metal, then bending the stretched annular portion toform a Wall upstanding from the surface of said piece of sheet metal,and then bending back the outer portions of said upstanding Wall intosubstantial parallelism with the inner portion of said upstanding Wall.

In testimony whereof I afliX my signature.
